Abstract

This application relates to a system for compression and mixing for hearing assistance devices by application of compression to individual sound sources before applying a head-related transfer function (HRTF) to prevent compression and cross modulation of interaural-level-difference (ILD) cues for localization, according to one example. Variations of the present system use coordinated compression to left and right individual source signals after application of HRTFs.
